The Flying Start programme aims to improve outcomes for children in some of the most deprived areas across Wales. This is done through providing four key Flying Start entitlements to children under four years old and their families: enhanced health visiting, parenting support, support for early language development primarily in the form of Language and Play programmes and free, high quality, part-time childcare for two to three year olds. This report is part of a series produced by Ipsos MORI and SQW for the national evaluation of Flying Start. It focuses specifically on the experiences of high need parents. Qualitative in-depth interviews with parents receiving Flying Start services were conducted between January and April 2013 in five different local authorities across Wales where the Flying Start programme is currently being delivered. 60 interviews were conducted in total, 30 with 'heavy' service users (defined as parents using the full entitlement, i.e. all four services), 15 with 'medium' service users (using enhanced health visiting support and two other service entitlements), and 15 with 'low' service users (using enhanced health visiting support only) (author abstract)
